  • i. up to 25m in height, and
  • ii. with an inter-storey drift of span/180 maximum, and
  • iii. the design ultimate limit state (ULS)differential wind pressure does not exceed 3.25 kPa, and
  • iv. with the stud spacing no more than 600mm centres
• d. located:
  
  • i. in all exposure zones (except microclimates) as defined in NZS3604:2011 section 4.2, and
  • ii. located anywhere in relation to the relevant boundary for building within the scope of:
    • C/AS1, Second edition, 2 November 2023 paragraph 1.1.1 or 
    • C/AS2, amendment 3, 2 November 2023 paragraph 1.1.1.

2. The system shall be specified, installed, inspected and maintained in accordance with the following sets of documents collectively referenced as the Applicable Technical Specification to the extent that their scope covers that for this Certificate:

• a. For direct fixed external wall cladding application:
  • i. James Hardie LineaTM Weatherboard Direct Fix Technical Specification (June 2023);
  • ii. Fire & Acoustic Design Manual (September 2024) by James Hardie section 4:16 Control of External Fire Spread, figures No’s. 2 to 11, 14 to 18 and 21 to 26, specifically details JHETGL30 and JHETGL60. These details have only been assessed and certified with respect to external fire spread via LineaTM Weatherboard. For walls located within 1.0m of a relevant boundary, LineaTM Weatherboard may be used as an external façade/cladding attached to the exterior of fire rated wall systems as depicted within the Fire and Acoustic Design Manual (November 2020). Fire Resistance rating performance of the wall assembly falls outside the scope of this certificate;
  • iii. BRANZ Appraisal No 446 (2020) LineaTM Weatherboard Direct Fixed Cladding.
• b. For cavity fixed external wall cladding applications:
  • i. James Hardie LineaTM Weatherboard Cavity Fix Technical Specification (June 2023);
  • ii. Fire & Acoustic Design Manual (September 2024) by James Hardie section 4:16 Control of External Fire Spread, figures No’s. 2 to 11, 14 to 18 and 21 to 26, specifically details JHETGL30 and JHETGL60. These details have only been assessed and certified with respect to external fire spread via LineaTM Weatherboard. For walls located within 1.0m of a relevant boundary, LineaTM Weatherboard may be used as an external façade/cladding attached to the exterior of fire rated wall systems as depicted within the Fire and Acoustic Design Manual (November 2020). Fire Resistance rating performance of the wall assembly falls outside the scope of this certificate;
  • iii. BRANZ Appraisal No 447 (2020) LineaTM Weatherboard Cavity Cladding.

(Note: Provisions within the documents above related to the use of the systems with steel-frame construction are outside the scope of this certification).

3. In wind zones greater than Very High a rigid air barrier which complies with Table 23 of E2/AS1 3rd Edition, amendment 10, 5 November 2020 shall be used. In Buildings exceeding 10 m in height RABTM Board must be used including horizontal control joints in accordance with the requirements of the CodeMark certificate for RABTM Board. (Refer to GM-CM30130).

4. The system is certified for use:

• a. with the ancillary components as described in this certificate, and
• b. with aluminium window and door joinery that is installed with vertical jambs and horizontal heads and sills. Only joinery compliant with the requirements of NZS 4211:2008 including amendment 1 for the relevant Wind Zone or wind pressure shall be used or have a current CodeMark

5. The weatherboards must only be installed horizontally on vertical surfaces.

6. All exposed faces, including top edges at sills and all bottom edges of LineaTM Weatherboard and fibre cement ancillary components must be finished with a latex exterior paint system complying with any of Parts 7, 8, 9, or 10 of AS 3730.

7. E2.3.5 and E2.3.6 compliance is limited to cavities created between the internal surface of the panels and the underlay or RABTM Board’s.
